Faxon Firearms Gunner BCG Ultra-Light Bolt Carrier Groups

$236.55

When looking at lightweight bolt carrier groups, they were unsatisfied with what the market had to offer. Seeing a capability gap, they set out to create a bolt carrier group that could live up to the GUNNER name with no compromise in strength or function. They set specifications that would allow no compromise:

  1. Lightest Weight Possible (8.32 Ounces Complete, 6.24 Ounces Carrier & Key Only)
  2. MIL-SPEC Materials & Finishes or Better!
  3. Forward Assist Serrations
  4. Compatible with Dust Covers
  5. Maintains Full-Auto Trip Sear for full-auto and the new multi-stage trigger functionality
  6. Looks Amazing


Matching their barrels, they've selected the QPQ method of Salt Bath Nitride for all the carriers components. By coating all parts, the carrier's natural slickness is increased markedly requiring less gas and pressure to operate. Further, the QPQ SBN process seals components against corrosion while making them fantastically wear resistant. 

As a testament of their trust, the carriers are all laser-engraved with the Faxon Shield after passing all Quality inspections.
